This instrument is a UV absorption analyzer designed specifically for ozone measurements. It uses a mercury lamp filtered for absorption at 254 nm as is typical of other commercial instruments. The design is very compact and uses the latest digital microprocessor technology. The unit automatically covers three ranges: 0 to 1, 0 to 10 and 0 to 900 ppm. Data output is via serial port, USB, 0-2.5 VDC, 4-20 mA. LCD digital display, and a time and date stamp digital data stream for external readout and data logging. Internal datalogger stores and transfers approximately four days of data.

Feature:
● Accurate enough for lab use, yet rugged enough for use in industrial conditions
● Autoranging
● LED indicators for on/off status, recalibration, and filter change
● Pre-calibrated
● Multiple outputs for downloading to PC options
